And this is what our customers say about their custom amps:

"The Thomsen Errorhead "three-channel" is the best allround amp I've ever used - it's like three boutique amps in one case. Whether in the studio or on stage - with the Thomsen there are no sound trade-offs."

Marcus Deml / Errorhead

"Since I use the Red Snake in the studio, making music is more fun than ever - it's the icing on the cake... what this top gear achieves in sound evolvement is marvellous... simply great!

In my 40 years of playing guitar I used countless amplifiers, but this thing rises above all of them... clean like a Plexi... depending on the gain, the overtones shift to a creamy, singing sound... then it sounds more "compressed" like a JCM 900 or almost without middles like an original JCM 2203 from the 80s... well, and then there's the ultimate rock sound I get out of the snake... that's my snake sound, which even an 800 can't produce... this amp is unmatched, qualitywise."
